The altering of the WCS format didn't have the slightest immediate effect on WCS America and after the completion of Challenger League, the number of local players continues to be diminutive. Four Canadians, four Americans and a single player from Mexico are all who'll represent the two continents in the upcoming WCS AM Premier League.

Even with the help of Chinese and Taiwanese players, the foreigners couldn't take the majority away from South Koreans and the latter will have seventeen players representing the country - just one less compared to Season 3 of last year. Nine of those came from the Challenger League matches as only Check, Apocalypse, Violet, Sage and Tassadar fell in the matches against non-Koreans.
